THE ORIGIN OF THE DOCTRINE OF THE TRINITY

 

The doctrine of the Trinity is utterly unique among all the views of God.  How did the Christian Church come to embrace such a unique view of God?  Most Christians assume that the Church came to understand the triune nature of God by examining the Scriptures and piecing together the evidence, and while this is partly true, it is not the whole story.

 

The doctrine of the Trinity, like all Biblical doctrines, is a revealed doctrine.  As we have said, a revealed doctrine is not discoverable by reason, and must be revealed to us by God if we are to understand it.  We know that God is triune because He has revealed Himself to us to be triune.  Otherwise we would have no way of knowing this.

 

The triune nature of God was revealed to us in history.  Specifically, it was revealed in the Incarnation and in the sending of the Holy Spirit.  In the Incarnation (lit. enfleshment), God clothed Himself in our flesh and lived among us, and the disciples beheld His glory (John 1:1-18).  Before His death and resurrection Jesus ("God with us", Matt. 1:23) promised that when He ascended to the throne He would send "another counselor" who would be with His Church forever (John 14:15-17). This promise was fulfilled when He poured out the Holy Spirit upon His Church on the day of Pentecost (Acts 2:29-33). Accordingly, the Son and the Spirit were each seen to be divine, and they were seen to be distinct from each other and from the Father (Romans 8:9; John 17). The triune nature of God was revealed in history just before the writing of the New Testament.

 

The Trinity is hinted at in the Old Testament, but never fully developed. In the NT the Trinity is never explained. The NT authors do not explain the doctrine precisely because they assume it everywhere.  They assume it because they had seen God the Son and had experienced God the Holy Spirit.
